T 0 alt whom it may concern: 7

Be it known that 1, WILLIAM J. CONWAY, a citizen of the United States, and a resident of the cit and county of San Francisco,

State of alifornia, have invented a new and useful invention-to wit, Improvements in Truck-Loading Devices, of which the following is a specification.

My invention has for its object means for simplifying the loading of trucks and the like, and is particularly adapted'to loading modern auto trucks with or withoutv a dump ing body and with the least expenditure of labor.

Other. objects will appear from the drawings and description which follow.

Figure 1 is a side elevation of a truck equipped with. my loading device.

Fig. 2 is a rear elevation of Fig. 1.

Fig. 3 is a detail of portions of myloading device. 1

Throughout the figures similar numerals refer to identical parts.

The frame of the. truck is shown by the V numeral 1 carried upon suitable springs 2-2 and mounted upon the wheels as 3, 4: and 5. Mounted upon the chassis is the body 6 adapted to convey loads. In trucks heretofore it has been difficult to lift the loads in place from the street level 7, and I therefore mountupon the body the pivoted members 8-9, pivoted as at 10-11 to the body 6 or if preferred it may be pivoted to the frame 1. These members normally occupy a substantiallyvertical position, and are each. connected as. by the side strap 12 with a horizontal member 13 also pivoted at 10, and which with the vertical members 89 formtwobell cranks operable about the pivots 10, 11, into any position as shown, for example bythe dotted lines 147-15.

Bridging the two members 8-9 I mount a horizontal truss 16 which may be adjusted to any desired position on 8, 9, as by the strap bolts 17-18 and which will swing from the full line position of Fig. 1 into the dotted line position by movement of and with the members 8 and '9. To the outer end of the member13 I attach a cable 18 passing around the pulley 19 and thence around the winding drum 20 which latter is rotated by the gear 21, pinion 22 and crank arm and handle 23, so that said cable may be wound or unwound as desired, drawing down the member from 15 into the position 13, and coincident therewith the member 8 from position 14 into position 8. Similar action occurs at the same time on the opposite side of the truck to move the member 9 as by the w nding of the cable 24 on the drum 25. It wlll be seen that the drums 20 and 25 are r1g1dly mounted upon the shaft 26 and are operable by winding the handle 23; also the members 8-9 may be turned backward as far as desired during which the truss 16 will descend over any desired load, see Figs. 1 and 3, as upon the ground 7 when the tackle 27 maybe employed to engage the said load,

and thereafter the two cables 18 may be re-.

wound on the drums 20 and 25 on each side of the truck by the operation of the handle 23, thus drawing down the two members from their dotted position as 15 to the full line positions as 13, and at the same time raising the load which now will swing with the truss 16 on to the floor 28 of the truck body. The device may also be used if desired for unloading by reversing the above operation.

I prefer to formthe strut or bars 12 with bolts at 29, 30, such that they may be readily removed and the members 8-9 hinged downward as in the direction of the arrow '31 when they will lie directly adjacent to during which the load will travel from its position as shown at 32 in the direction of the arrow 33 until it has arrived upon the truck at 28. It will be seen that this can readily be accomplished by one operator even when the load is of considerable weight or bulk as compared with two or more men necessary without my loading device.

By locating the pivots 10, 11 on the body of a truck which body is in turn pivoted to the frame-of said truck, the body may be used to dump the load in the well known way in which case it is raised as through the are 34 without disturbing the lQacling device.

I claim:

1. In a loading device for trucks and the like, a vertically disposed lever pivoted at its lower end on each side of said truck, a truss between said levers, a horizontally disposed member on each side and carried by the aforesaid pivots and connected as a bell crank With the corresponding lever operating means for said members whereby the levers are rotated about their pivots through an angular movement whereby a load suspended from said truss may be raised or lowered, wherein the truss is vertically adjustable to various positions 011 the levers.

2. Apparatus as set forth in claim 1, wherein the connection between each lever and membermay be disconnected permitting the lever to be folded down adjacent the member thus collapsingthe device when out of" use.

In testimony whereof,I have hereunto set my hand at San Francisco, California, this 13th day of August, 1920.
